Retro-Reflective Performance
V-REFLEXTM Reflective Material - Low Temperature Heat Transfer Reflective Film exceeds the minimum retro-reflective requirements of EN ISO 20471, ANSI/ISEA 107 Level 2 (and other norms that are inherent from them), when tested at e = 0° or e = 90° in accordance with the procedures stated on standards.
Minimum coefficients of retro-reflection required by standards are shown as below table. (Coefficient of Retro-reflection * (R’ or RA ) cd/lux/m2)
